Prevention And Maintenance Tips
Run Cold Water: Always run cold water while using the garbage disposal to help flush waste down the drain.
Avoid Fibrous Foods: Keep fibrous foods like celery, corn husks, and onion skins out of the disposal, as they can cause jams.
No Grease or Oil: Never pour grease or oil down the disposal as it can solidify and cause clogs.
Dispose of Bones Properly: Do not put bones in the garbage disposal, as they can break the blades or cause jams.
Clean Regularly: Clean your garbage disposal regularly by grinding ice cubes and lemon peels to keep it fresh and free of debris.

Garbage Disposal FAQs
1. What causes a garbage disposal to hum but not grind?
A humming garbage disposal usually indicates a jam or a stuck impeller. The motor is still running, but the grinding mechanism is unable to move due to a foreign object or built-up food debris. The humming sound is a result of the motor trying to turn the impeller but being unable to do so.
2. Is it safe to use a garbage disposal that’s humming?
No, it is not safe to use a humming garbage disposal. The humming indicates that the disposal is jammed, and continued use may lead to motor burnout, which can cause irreversible damage. Turn off the power to the disposal immediately and address the issue before attempting to use it again.
3. How can I fix a garbage disposal that’s humming but not working?
To fix a humming garbage disposal, follow these steps:
- Turn off the power and unplug the disposal.
- Inspect the grinding chamber for visible obstructions.
- Use a plunger or Allen wrench to free the impeller.
- Press the reset button on the bottom of the unit.
- Test the disposal to ensure it’s working properly.
If these steps don’t resolve the problem, consult a professional plumber.
4. Can a humming garbage disposal be a sign of a bigger problem?
While a humming garbage disposal is often a sign of a jam or stuck impeller, it may also indicate a more serious issue, such as a failing motor or damaged internal components. If you have tried the steps mentioned above and the disposal is still humming, it’s best to call a professional plumber to diagnose and fix the issue.
5. How can I prevent my garbage disposal from humming in the future?
To prevent your garbage disposal from humming, follow these tips:
- Run cold water before, during, and after using the disposal.

Garbage disposal – I have done all the troubleshooting and can only get the hex wrench to go half way.
Have cleaned out teeth, nothing in each groove, but still won’t grind, hums only like it is on but no grinding noise to indicate it’s working. Did hot water, soap and vinegar try also, nothing. Is next step removal???
The Allen wrench really worked. For some reason, there were pieces of a plastic cup in the disposal. I removed all that I could, and then tried the wrench. Worked, but it made a noise when it was running. I think there is something still in there, but will use the ice cubes as suggested to clear out any remaining pieces of plastic. Thanks.
My garbage disposer hums when I turn it on. The hex bar won’t let me spin it. I’ve inspected it and I can’t find anything stuck. I also tried the baking soda/vinegar/hot water thing twice. I also tried pressing reset button. It’s an Insinkerator brand that’s about 2 years old. Any recommendations? I only want to call a plumber as a last resort.
Thanks so much for this video. This problem started this morning. The fix using the wrench worked for me. How did you know I was about to have a party :-)
